Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Safe for cats?
Answer by ChewyJan 21, 2020
To use the Hartz Ultra Guard Flea & Tick Home Spray use the spray in homes, garages, attics, apartments and hotel. Hartz do not advise spraying pets directly. Any room being sprayed should not be used by any person or pet in the home for at least 2 hours after treatment, the room should be aired out for several hours before any person or pet in the home is exposed to the room.

After spray on furniture or bedding, can the animal get on the furniture/bedding after?
Answer by ChewySep 04, 2019
We recommend waiting at least an hour before letting your pet return to the treated areas.

Can this be used on carpets?
Answer by ChewyJul 15, 2019
This spray is gentle enough to be used on carpet and upholstery.

Works good

I used it all over my house and it works good. The smell was not overwhelming like others I have tried.

Doesn't work

I honestly got it because it was cheap, but it doesn't do a thing. I even used near half the bottle (fighting with a broken spray nozzle) just to make sure, but the fleas kept jumping. Waste of money.

Flea Spray

Not sure how long it takes to take effect but it was not working, sprayed couple times and the fleas were still around.

Great product

First time using this product and it's worked really well. The only thing I would want changed is the way it sprays, you have to really get close to the objects you wish to spray and for people like me bending over especially low is quite painful. I would have rated it a five if not for the light mist close to object spraying.

Doesn't Work

Only good thing about this is it smells good. I bought 2 bottles (at the suggestion of Chewy) and have repeatedly sprayed and sprayed and sprayed everything my pets lie on or are around. Even though I've used this, along with topicals and even Seresto, we still have fleas!

Not worth it

Just spayed for a second time and had a baby flea jump on me when I went to check if it dried. Started doubting it even kills them.
